Latest updates for the neighborhood sewer project

St. Johns – Cathedral Park Sewer Repair Project Update: November 9, 2018

Environmental Services has begun construction on a project to repair over 11,000 feet, or about 2 miles, of public sewers in the St. Johns and Cathedral Park neighborhoods. Many of the sewer pipes are about 80 years old and deteriorating due to age. This investment in your neighborhood will allow for continued dependable sewer service and protect the public and our environment by reducing the possibility of sewage releases to homes, businesses and streets.

CONSTRUCTION SCHEDULE

Construction began mid-September 2018 and will take about a year to complete. Depending on the location and construction method, work could last up to a month or more in one area. For the most up-to-date information and map of the project schedule, visit www.portlandoregon.gov/bes/StJohnsCPark.

CONSTRUCTION METHODS

The city uses many construction methods to repair or replace sewer pipes. For the upcoming sewer line repairs, the city plans to use Open Trench Excavation. To learn more about different constructions methods and what can be expected during construction, go to www.portlandoregon.gov/bes/methods.

 

WHAT TO EXPECT DURING CONSTRUCTION

We have started some pre-construction activities and you may see crews working in your neighborhood. Activities could include documenting pipe conditions via video cameras; fencing off trees for protection; tree trimming; equipment use and storage; noise, vibration and dust; traffic delays, and parking restrictions.

 

Typical work hours are 7:00 a.m. to 6:00 p.m. Monday through Friday, but the contractor may schedule work during the same hours on Saturdays.

 

Residents and businesses should expect periods of inactivity between phases of work, ranging from a few days to a few weeks. In areas where the repair requires a trench, temporary pavement will be applied to the site until permanent pavement can be applied at a later date. The duration of any period of inactivity depends on a variety of variables including underground conditions, weather, traffic impacts, subcontractor schedules, quality control tests, and availability of materials. In the event of a sewer backup, storm drainage problems or clogged catch basins, call 503-823-1700.
